Pressure-cooking device

An unpowered pressure-cooking device, comprising:

• a) a base pot having a plurality of shells, the shells hermetically sealed together and forming a cavity therebetween and forming a receptacle thereinside;
• b) an inner pot shaped and sized to rest within the receptacle of the innermost shell and is selectably removeable therefrom, wherein the inner pot leaves a gap between the bottom of the inner pot and the bottom of the innermost shell when resting within the innermost shell;
• c) a nonmetallic removable thermal body shaped to fit within the gap, wherein the thermal body is the sole and only heating element of the unpowered pressure-cooking device;
• d) a cover having a gasket shaped and positioned to hermetically seal an inside portion of the pressure-cooking device when closed, wherein the unpowered pressure-cooking device does not include any electrically powered heating elements;
• and
• e) a pressure relief mechanism positioned to be in functional communication with an interior of the inner pot when the inner pot is disposed within the base pot, the pressure relief mechanism extending through the cover from a top surface thereof to a bottom surface thereof.
